CHAPTER 1 A Very Short Tour of Game Theory
interactive situation. Solution concepts are proposed, and natural issues like existence
and uniqueness of the solution(s) are considered. For a given wireless scenario,
it may be that no suitable solution concept is available in the current literature of game
theory. This does not necessarily mean that game theory is not the right approach;
it is more likely that the theory needs to be enriched. To this end, the authors would
like to draw to the attention of the reader who is new to game theory, that it is not
only about:
1. rational decision-makers;
2. selfish decision-makers;
3. non-cooperative games;
4. Nash equilibrium as a solution concept;
5. interactions due to the fact that the players’ utility depends on the actions of the
others.
Some elements justifying these assertions are given throughout this chapter, especially
in Sec. 1.5.
